qcacld-3.0: Resolve invalid memory access while processing GET STATES IOCTL

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

While processing GET STATES IOCTL, in a while loop, HOST prints PE, LIM
and MLM states of each session. Normally while loading, HOST allocates
memory for five sessions, but while processing this IOCTL, it iterating
in a loop assuming there are 255 sessions allocated, leading to crash
because of invalid memory access.
Hence while printing PE, LIM and MLM states iterate only for allocated
number of sessions.
